Answers to common questions about DMARC Monitoring.
DMARC Monitoring collects DMARC aggregate (RUA) and TLS-RPT reports for your sending domains and presents them as dashboards and alerts. Rather than managing raw XML in a mailbox, you get authentication rates, source breakdowns, policy trends, and notifications when something changes.
When you publish a DMARC record with an RUA address, mailbox providers send aggregate reports summarizing every message they received that used your domain in the From address. Each report includes sending IP addresses, message counts, SPF and DKIM results, and the policy action applied. Google, Microsoft, Yahoo, and most other providers send these daily as gzipped XML attachments, which are difficult to read without dedicated tooling.
TLS Reporting (TLS-RPT) is a standard that allows mail servers to report delivery failures caused by TLS negotiation problems, including STARTTLS downgrade attempts and MTA-STS policy violations. When you publish a TLS-RPT record, participating mail providers send JSON reports detailing failures encountered during secure delivery to your domain. DMARC Monitoring collects these alongside DMARC reports to give a unified view of your domain's email security posture.
RBL Monitoring checks whether your IPs and domains appear on email blocklists, affecting deliverability. DMARC Monitoring focuses on authentication: who is sending mail as your domain, whether SPF and DKIM are aligned, and whether your policy is being enforced. They are complementary products addressing different problems.
Planned alerts include authentication failure rate spikes, new unauthorized source IPs, a previously passing source failing SPF or DKIM alignment, unexpected DMARC or TLS-RPT policy record changes, and TLS-RPT delivery failures. Alerts are delivered through the same channels as other Generator Labs products: email, Slack, PagerDuty, webhooks, and more.
DMARC Monitoring is planned for launch in 2026. Contact us to be notified when it becomes available.
